Chen Yinque's "four don't talk" is.

I won't say what my predecessors said; I don't say what the neighbors said; I don't say what foreigners have said; I said it myself in the past, and I won't say it.

Chen Yinque's "Four Don't Speak" can be said to be a peak of teachers' lectures. It is not easy to do one of these things. To achieve "four don't talk", you must first fully understand what your predecessors and neighbors have said. This requires a lot of reading, a lot of knowledge and memory, and studying hard at a cold window. As long as you finish this work, you will become a great university scholar.

You should also know what foreigners have said. Proficient in many foreign languages, "learning Chinese and western", of course, well deserved. Then put forward your own new ideas, new research results, every day, every class has new ideas and opinions, which is even more difficult. However, Chen Yinque has achieved the "four stresses" and is worthy of being a master of Chinese studies and literature and history.
